And this was in his first year of high school basketball.
In June he was invited to the Nike Elite 100 and finished second in the camp in scoring, earning praise from Scout.com as "arguably the top overall prospect."
Earlier this month he was one of only three Class of 2015 players to be invited to the LeBron James Skills Academy and that same week proceeded to earn the No. 2 overall ranking in his class by Scout.com.
"I notice it but I try to stay humble about the whole thing and don't think about it," Stone said.
This week Stone has joined The Family 16-under roster to compete in Nike's Sweet 16 Tournament at the EYBL Finals. Despite all of his accomplishments this year, a new team in an older age bracket is still a learning experience.
"It's been challenging," Stone said after a frustrating, foul-plagued performance in his opening game. "A lot of guys are stronger than me, more experienced. I'm learning how to be aggressive but get foul calls."
When Stone's game is clicking, he's showcasing a diverse set of post moves, hitting face-up jumpshots and dutifully defending the rim on the other end. That's why he's already got offers from Wisconsin, Marquette and DePaul, and lists interest from UCLA, Georgetown, Indiana, Michigan, Michigan State, and North Carolina.
North Carolina's early interest came in the form of a phone call to his father by UNC assistant coach Steve Robinson.
"My dream school was UNC," Stone volunteered.
The reason? Family influence.
Stone's father, Robert, was a standout player at UW-Whitewater and has educated his son on the game and its history, including the Tar Heels.
Stone listed Michael Jordan and James Worthy from the '80s, Vince Carter from the '90s, and James Michael McAdoo from UNC's current roster.
"My family, they like the ACC, the conference," Stone said. "My dad taught me how to play basketball and everything he knew."
